Abstract
PURPOSE The aim of this study is to investigate the effect of vitreomacular interface disorders (VMID) on treatment response in patients treated with anti-vascular endothelial growth factor (anti-VEGF) due to diabetic macular edema (DME). METHODS Three hundred seventy-seven eyes of 239 patients in the MARMASIA Study Group who received intravitreal anti-VEGF treatment (IVT) due to DME were included in the study. The group 1 consisted of 44 eyes of the patients who had not received any treatment before, were followed up regularly for 24 months after at least a 3-month loading dose, and suffered from VMID such as epiretinal membrane, vitreomacular adhesion or traction, and lamellar hole. The group 2 consisted of 333 eyes of the patients without VMID. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) of the patients at baseline, 3rd month, 6th month, 1st year and 2nd year follow-ups were measured. RESULTS The mean age of the Groups 1 and 2 was 67.1 ± 11.3 and 61.9 ± 10.2 years, respectively. 61.3% of the group 1 and 58.8% of the group 2 were female (p > 0.05). The duration of diabetes was 19.2 ± 3.7 and 15.8 ± 3.2 years, respectively, and the number of follow-ups was 16.09 ± 4.68 and 12.06 ± 4.58, respectively in the groups (p < 0.001, 0.001, respectively). The number of IVT was 7.13 ± 2.71 and 7.20 ± 2.22, respectively in the groups 1 and 2 and no statistically significant difference was observed between them (p = 0.860). According to logMAR, BCVA values at baseline were 0.63 ± 0.24 and 0.59 ± 0.26 (p = 0.29), respectively, in the groups and the amount of change in BCVA at the end of the 2nd year was - 0.02 ± 0.48 in the group 1 and - 0.12 ± 0.48 in the group 2. It was observed as 0.48 (p = 0.13). Although the increase in BCVA was greater at all follow-ups in the group 2 compared to their initial examination, no significant difference was observed between the groups in terms of BCVA change. The CMT values of the groups at baseline were 442.5 ± 131.3 µm and 590.9 ± 170.6 µm, respectively (p = 0.03) The decrease in CMT after IVT was significantly greater in the group 2 at all follow-ups when compared to the first group (p < 0.05). CONCLUSION While the presence of VMID in DME patients receiving IVT did not affect visual results, it negatively affected the anatomical response and macular edema morphology. The presence of VMID at baseline affected the success of IVT. It should be taken into consideration that VMID may resolve spontaneously or with IVT, and new cases of VMID may occur in patients during the treatment process.

Abstract
BACKGROUND This study aimed to assess the influence of vitreoretinal interface (VRI) on the outcome of Brolucizumab intravitreal injections (IVBr) in patients with age-related macular neovascularization (MNV). METHODS 40 eyes of 40 patients with active-naive MNV candidates to IVBr were enrolled at the Ophthalmology Clinic of the University "G. d'Annunzio," Chieti-Pescara, Italy. Based on the VRI condition, 20 patients were included in the G0 group (without evidence of VRI alterations), whereas 20 patients were enrolled in the G1 group (with VRI abnormalities). The primary outcome measures were changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SCT), pigment epithelial detachment presence and maximum height (PEDMH), intraretinal fluid (IRF) presence, subfoveal subretinal fluid (SSRF) presence and thickness (SSRFT), subretinal pigment epithelium fluid (SRPEF) presence and SRPEF thickness (SRPEFT). RESULTS There were no significant differences in BCVA and SCT between the two groups, although both parameters significantly changed over time (BCVA p 0.005; SCT p < 0.001). No differences in CMT and PEDMH were found between the two groups. SSRF presence showed differences between the two groups at T4 (p 0.044), and IRF presence showed significant differences over time (p 0.008) in favor of MNV eyes without VRI alterations. CONCLUSIONS Concomitant vitreomacular interface disease alterations in eyes treated with IVBr for MNV influenced fluid presence with greater persistence of SSRF and IRF compared to MNV eyes without VRI. Nevertheless, the overall macular thickness and visual function were not significantly different between the two groups.

Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06518-6. [PMID: 38771336 DOI: 10.1007/s00417-024-06518-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 03/05/2024] [Accepted: 05/09/2024] [Indexed: 05/22/2024] Open
Abstract
BACKGROUND The influence of Vitreomacular Interface Abnormalities (VMIA) such as Epiretinal Membrane (ERM) and/or vitreomacular traction (VMT) on the response of patients with Centre Involving Diabetic Macular Edema (CIDME) to standard of care Anti-VEGF medications is under-researched. The aims of this study were: 1) To determine the incidence of VMIA at baseline and 12 months amongst treatment naive patients commencing anti-VEGF treatment 2) To compare the response to Anti-VEGF medications at 3 monthly intervals for 12 months in a large cohort of patients with and without VMIA on their baseline OCT scan. Response was determined in terms of: number of injections, central macular thickness and visual acuity. METHODS A retrospective case notes review of treatment naïve patients with newly diagnosed CIDME. Included patients had been commenced on intravitreal Anti-VEGF injections (ranibizumab or aflibercept) at a single centre. Inclusion criteria were: treatment naïve DME patients with a CMT of 400μ or more receiving anti-VEGF treatment with at least 12 months follow up and in whom macular OCT scans and visual acuity (VA) measurements were available within two weeks of baseline, 3, 6, 9 and 12 months. Exclusion criteria included: previous intravitreal therapy, previous vitrectomy, cataract surgery during the follow-up period, concurrent eye conditions affecting vision or CMT. RESULTS 119 eyes met the inclusion criteria and underwent analysis. Groups were comparable in their baseline demographics. Baseline CMT measurements were comparable at baseline (417μ and 430μ in the No-VMIA and VMIA groups respectively) and improved to approximately 300μ in both groups. From 6 months CMT continued to improve in the no-VMIA while progressively deteriorating in the VMIA group. Change in CMT was statistically different at 12 months between the 2 groups (108μ and 79μ, p= 0.04). There was a mean of 7 injections after 12 months. CONCLUSION Our study has shown a 46% incidence of VMIA amongst patients newly diagnosed with centre involving DME undergoing treatment with anti-VEGF injections. We have also demonstrated a significant difference in CMT and VA response to anti-VEGF treatment in patients with and without VMIA. Initial response was similar between the 2 groups up until 6 months. From 6 to 12 months significant differences in treatment response emerged. Differences in clinical response between patients with and without VMIA may help guide further prospective controlled studies and optimise treatment strategies.

Abstract
Objective To investigate the systemic and ocular factors that affect the response to intensive aflibercept treatment in diabetic macular edema (DME) in a real-world setting. Methods This retrospective cohort study evaluated 30 eyes of 23 patients with DME who underwent intensive intravitreal aflibercept injections (five monthly loading doses). Treatment response was assessed by central retinal thickness (CRT) and best-corrected visual acuity (BCVA) at each monthly visit. The patients were categorized as good (<300 μm) and suboptimal (≥300 μm) responders based on CRT after the loading phase. Baseline systemic and ocular factors associated with treatment response were investigated. Results The mean CRT and BCVA significantly improved after five loading injections (486.87 ± 95.46 to 334.90 ± 69.47 μm and 0.51 ± 0.30 to 0.35 ± 0.25 LogMAR, respectively, all p < 0.05). During 12 months of follow-up, 16 eyes (53.33%) maintained CRT without additional treatment. Eyes with diabetes mellitus (DM) for ≥15 years, estimated glomerular filtration rate (eGFR) < 80 mL/min/1.73 m2, serum creatinine ≥ 0.95 mg/dL and potassium ≥ 4.7 mmol/L, and presence of epiretinal membrane (ERM) were more likely to have a suboptimal response to the treatment. Conclusions Five monthly loading doses of intravitreal aflibercept injection provided significant anatomical and visual improvements in patients with DME. Patients with longer DM duration, lower eGFR, higher serum creatinine or potassium levels, or ERM were predisposed to a suboptimal treatment response. Individual response to intensive aflibercept treatment for DME can be predicted by these systemic and ocular risk factors.

Evaluating the effect of vitreomacular interface abnormalities on anti-vascular endothelial growth factor treatment outcomes in diabetic macular edema by optical coherence tomography: a systematic review and meta-analysis. Photodiagnosis Photodyn Ther 2023; 42:103555. [PMID: 37088331 DOI: 10.1016/j.pdpdt.2023.103555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 04/02/2023] [Accepted: 04/03/2023] [Indexed: 04/25/2023]
Abstract
PURPOSE To evaluate the effect of vitreomacular interface (VMI) configuration on treatment outcomes after intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for diabetic macular edema (DME) using optical coherence tomography (OCT). METHODS A systematic literature search was performed on PubMed, Embase, web of science and clinicaltrials.gov. The primary outcome parameters were central macular thickness (CMT), best-corrected visual acuity (BCVA) and mean injection numbers. We performed this meta-analysis by Review Manager (RevMan) 5.4.1. RESULTS The impact of epiretinal membrane (ERM), vitreomacular traction (VMT) and vitreomacular adhesion (VMA) on the treatment outcomes were analyzed separately. 9 clinical studies involving 699 eyes were eligible for the meta-analysis for evaluating the effect of ERM/VMT on efficacy. And 7 studies with 610 eyes were included to access whether VMA affected the response to anti-VEGF therapy in patients with DME. The ERM/VMT group had poorer CMT reductions than the control group at 1 month ([MD] 52.91mm, P<0.00001), while no significant difference at 3 months ([MD] 43.95 mm, P=0.22) and over 12 months ([MD] 30.51 mm, P=0.45). No statistically significant difference in the mean BCVA change at 1 month ([MD] -0.03 Log MAR, P=0.79), whereas ERM/VMT group had poor visual acuity gains at 3 months ([MD] 0.08 Log MAR, P=0.003), and a tendency of poor vision improvement over 12 months follow-up ([MD] 0.07 Log MAR, P=0.11). There was no significant difference in the visual and anatomical results over 3 months in DME patients with or without VMA ([MD] -21.92 mm, P = 0.09; [MD] 1.79 letters, P=0.22). Besides, VMI configuration was not found to affect mean injection numbers. CONCLUSION The limited evidence suggested that ERM/VMT was associated with worse CMT reduction at 1 month, poor BCVA gain at 3 months and a tendency of limited vision improvement over 12 months follow-up in DME patients treated with anti-VEGF agents. And VMA may not adversely affect the anatomic and functional outcomes. However, the results of this meta-analysis should be interpreted with caution because of the heterogeneity among study designs.

Abstract
BACKGROUND Intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections are the standard of care for diabetic macular edema (DME), a common complication of diabetes. This study aimed to identify factors influencing DME intravitreal anti-VEGF treatment outcomes in real-world practice. METHODS This was a multi-center retrospective observational study using medical chart review of participants receiving anti-VEGF injections for DME (N = 248). Demographic and clinical variables were assessed for association with best corrected visual acuity (BCVA) and central macular thickness (CMT) outcomes using regression models. RESULTS There was a significant improvement in BCVA (p < 0.001) and CMT (p < 0.001) after 12 months of treatment, although 21% of participants had decreased BCVA, and 41% had a < 10% CMT reduction at 12 months. Higher baseline BCVA (p = 0.022, OR=-0.024, 95% CI=-0.046,-0.004) and longer duration of diabetic retinopathy (p = 0.048, OR=-0.064, 95% CI=-0.129,-0.001) were negative predictors for BCVA response, whereas Aflibercept treatment (p = 0.017, OR = 1.107, 95% CI = 0.220,2.051) compared with other drugs and a positive "early functional response" (p < 0.001, OR=-1.393, 95% CI=-1.946,-0.857) were positive predictors. A higher baseline CMT (p < 0.001, OR = 0.019, 95% CI = 0.012,0.0261) and an "early anatomical response", (p < 0.001, OR=-1.677, 95% CI=-2.456, -0.943) were predictors for greater reduction in CMT. Overall, the variables could predict only 23% of BCVA and 52% of CMT response. CONCLUSIONS The study shows a significant proportion of DME patients do not respond to anti-VEGF therapy and identifies several clinical predictors for treatment outcomes. TRIAL REGISTRATION The study was approved through the Human Research Ethics Committee, University of Tasmania (approval number H0012902), and the Southern Adelaide Clinical Human Research Ethics Committee (approval number 86 - 067).

Anti-angiogenic therapy in the treatment of diabetic macular edema in various variants of the vitreoretinal interface. OPHTHALMOLOGY JOURNAL 2023. [DOI: 10.17816/ov114733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND: Anti-angiogenic therapy for diabetic macular edema (DME), recognized as the gold standard, is not always effective. When compensating for the general somatic status, it is necessary to search for local causes of DME resistance to anti-angiogenic therapy.
AIM: To study the effectiveness and features of anti-angiogenic therapy for DME in normal and pathological vitreoretinal interface (VRI).
MATERIALS AND METHODS: Patients who received anti-angiogenic therapy for 12 months, in addition to the standard examination, underwent optical coherence tomography with an assessment of morphometric parameters and VRI.
RESULTS: In addition to the groups of normal and pathological VRI, a group of transformation from pathological to normal VRI was identified. Visual acuity increases with normal VRI, decreases with pathological. OCT scores decrease in both groups. In the transformation group, an increase in vision and a decrease in OCT parameters were observed only after VRI transformation.
CONCLUSION: The pathologic condition of the VRI reduces effectiveness of anti-angiogenic therapy for DME, except for 10% of cases in which VRI is transformed into normal within 5-6 months from the start of treatment. These data should be taken into account when choosing a treatment strategy for DME.

Abstract
PURPOSE To compare efficacy of simultaneously administered intravitreal dexamethasone implant (DEX implant) and ranibizumab (simultaneous double protocol) injections with ranibizumab monotherapy for diabetic macular edema (DME) at month 24. METHODS This is a prospective, consecutive, clinical interventional study. Naïve eyes with DME were randomized into two groups: 34 eyes received simultaneous double-protocol therapy and 34 eyes received ranibizumab monotherapy. The primary efficacy endpoint was change in visual acuity in month 24. The secondary efficacy endpoints were to evaluate gain of ≥15 letters, morphological changes and central foveal thickness. Decreased vision from DME (study eye BCVA, 20/40 or worse Snellen equivalent using ETDRS testing), the presence of DME with ≥300 μm foveal intraretinal cystoid spaces (within 1000 μm of the centre of the fovea), subfoveal neuroretinal detachment (SND), intraretinal hyperreflective foci (HRF, within 500 μm of the centre of the fovea) or foveal lipid exudates and external limiting membrane (ELM) and ellipsoid zone (EZ) disruption (within 500 μm of the centre of the fovea) on SD-OCT were eligible to enrol. RESULTS The mean baseline BCVA was 48 ± 23 letters in double protocol group and 52 ± 14 letters ranibizumab monotherapy group (p = 0.416). The mean number of ETDRS letters changed from baseline at 12 months versus change from baseline at month 24 in double protocol group and ranibizumab monotherapy group were +21.6 versus +20.2 and +9.6 versus +9.1, respectively. At the month 24 time point, 65.4% of patients in double protocol group and 26.2% of patients in ranibizumab monotherapy group had gained ≥15 ETDRS letters in BCVA from baseline (p < 0.001). The external limiting membrane (ELM) and ellipsoid zone (EZ) integrity were better in the double protocol group in comparison to ranibizumab monotherapy group at month 24. In addition, there was no statistically significant increase in the proportion of patients with epiretinal membrane in double protocol group at month 24, by the contrast with ranibizumab monotherapy group (p = 0.06 and p = 0.04 in the double protocol and ranibizumab monotherapy groups, respectively). From baseline to month 24, the mean central foveal thickness (CFT) was 672 ± 293 μm reduced to 278 ± 84 μm in double protocol group and was 631 ± 279 μm reduced to 356 ± 108 μm in ranibizumab monotherapy group (p < 0.001 and p < 0.001). From baseline to month 24, 38% (13/34) of eyes in double protocol group and 18% (6/34) of eyes in ranibizumab monotherapy group had at least 5 mmHg of IOP elevation (p = 0.012). Two grades or more increased cataract density were detected 27% (6/22) of eyes in the double protocol group and in 12.5% (3/24) of eyes in the ranibizumab monotherapy group from baseline to month 24 (p = 0.032). CONCLUSION According to the improvements in visual acuity and morphological changes achieved at month 24, the simultaneous double protocol therapy can be an effective treatment option for DME with inflammatory biomarkers on OCT or/and decreased visual acuity.

OCT-Based Biomarkers are Associated with Systemic Inflammation in Patients with Treatment-Naïve Diabetic Macular Edema. Ophthalmol Ther 2022; 11:2153-2167. [PMID: 36166152 DOI: 10.1007/s40123-022-00576-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Accepted: 09/12/2022] [Indexed: 10/14/2022] Open
Abstract
INTRODUCTION Diabetic macular edema (DME) is one of the major sight-threatening complications of diabetic retinopathy, which is associated with retinal inflammation. However, it is still unknown whether DME is associated with systemic inflammation. The study aimed to investigate the association between systemic inflammatory and optical coherence tomography (OCT) biomarkers in patients with treatment-naïve center-involving diabetic macular edema (DME) and to further explore the role of systemic inflammation in DME. METHODS Medical records including clinical characteristics and ophthalmic examinations were collected from patients with treatment-naïve center-involving DME. Systemic inflammation markers including systemic immune-inflammatory index (SII), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were calculated. OCT biomarkers, including intraretinal cyst (IRC) size, disorganization of retinal inner layers (DRIL), external limiting membrane (ELM)/ellipsoid zone (EZ) integrity, retinal hyperreflective foci (HRF), subretinal fluid (SRF) and vitreomacular (VM) status were evaluated manually. Correlation analysis and multivariable linear regression models were used to investigate the relationship between systemic inflammatory markers and OCT biomarkers. RESULTS A total of 82 patients with treatment-naïve center-involving DME were included. The number of HRF on OCT was correlated with SII, NLR, and PLR and positively associated with SII (p < 0.001) in both univariate and multivariate linear regression analyses. The differences remained largely the same during subgroup analysis controlling DM duration, SRF, and ELM/EZ integrity. No significant association was observed between other OCT biomarkers and blood inflammatory markers. CONCLUSION Retinal HRF in diabetic macular edema is associated with blood inflammatory markers, which supports the theory of HRF's inflammatory nature and emphasizes the important role of inflammation in DME. SII may be a potential marker for DME treatment decisions.

Factors associated with diabetic macular edema in patients with proliferative diabetic retinopathy. Graefes Arch Clin Exp Ophthalmol 2022; 260:2191-2200. [PMID: 35192029 DOI: 10.1007/s00417-022-05595-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 12/23/2021] [Accepted: 02/15/2022] [Indexed: 11/04/2022] Open
Abstract
PURPOSE To identify factors associated with diabetic macular edema (DME) and to characterize the types of DME present in eyes with proliferative diabetic retinopathy (PDR). METHODS Observational, retrospective case series of PDR patients reviewed for demographic information, general medical history, ophthalmologic history, optical coherence tomography (OCT), and fluorescein angiogram image characteristics. DME and vitreomacular interface (VMI) status were determined using OCT images. DME was defined as center-involving DME (CI-DME) and noncenter-involving DME (NCI-DME). VMI was defined as vitreomacular adhesion (VMA), vitreomacular traction (VMT), or macular posterior vitreous detachment (PVD). RESULTS A total of 293 eyes of 210 screened patients with PDR were included. Of the eyes, 194/293 (66.2%) had DME, and 99/293 (33.8%) had no DME; in univariable analysis, there were no significant differences in VMI status (p = 0.4) or epiretinal membrane (ERM, p = 0.1) between them. Of 194 eyes with DME, 90/194 (46.4%) had CI-DME, and 104/194 (53.6%) had NCI-DME. In univariable analysis, CI-DME eyes were significantly more likely than NCI-DME eyes to have a PVD (p = 0.029) and ERM (p < 0.001). In multivariable analysis, the presence of younger age (p = 0.028) and presence of ERM (p = 0.001) were significantly more likely to be observed in eyes with CI-DME. CONCLUSION In this exploratory study focused on diabetic patients with PDR, we determined that VMI status did not have a significant association with DME in general, but VMI status, younger age, and presence of ERM may be associated with CI-DME.

Abstract
Background. Diabetic macular edema (DME) is one of the main causes of decreased central vision. Determining the reasons for the refractoriness of DME to treatment is an urgent problem.Aims. Based on the analysis of optical coherence tomography, to study the features of pathological changes in the retina and vitreoretinal interface (VRI) in the macular zone in patients with DME.Materials and methods. We studied 587 patients (587 eyes) with diffuse DME in the setting of nonproliferative diabetic retinopathy. In addition to the standard ophthalmological examination, everyone underwent optical coherence tomography of the macular zone with an assessment of structural changes in the retina, morphometric parameters, and the state of the VRI.Results. In 351 patients (59.80 %) with DME, pathological variants of the VRI were revealed, in which the best corrected visual acuity was significantly lower, and the morphometric parameters (retinal thickness and macular volume) were signifi cantly higher. Analysis of morphostructural changes in the macular zone revealed that in pathological VRI, neuroepithelial detachment and high edema are more common, and cystic edema is larger in area compared to the group with a normal VRI. With detachment of neuroepithelium against the background of a pathological VRI, the worst morphometric data are determined, with solid exudates in the macula, the worst indices of visual loss are determined.Conclusions. The pathological VRI in patients with diabetic macular edema occurs in more than half of the cases and is characterized by a high incidence of neuroepithelial detachment, high edema, higher morphometric parameters with worse visual acuity. At the same time, the presence of neuroepithelial detachment corresponds to the worst morphometric indicators of the macular zone, and the presence of solid exudates corresponds to a lower maximum corrected visual acuity. Further research is needed to assess the effect of the listed morphostructural and morphometric changes in combination with various pathological variants of VRI on the effectiveness of DME treatment.

Abstract
Purpose To compare the efficacy of pars plana vitrectomy (PPV) versus intravitreal injection (IVI) of ranibizumab (RBZ) in the treatment of diabetic macular edema (DME) associated with vitreomacular interface abnormalities (VMIA). Methods The records of patients presenting with DME and VMIA throughout 2016 to 2018 were retrospectively analyzed. The patients were divided into 2 groups: group I received IVIs of RBZ and group II underwent PPV with internal limiting membrane peeling. The main outcome measures were the change in the LogMAR corrected distance visual acuity (CDVA) and central subfield thickness (CSFT) on optical coherence tomography over 6 months. Results At 6 months, mean CDVA improved by 0.22 ± 0.21 in group I patients (p < 0.001), while in group II, it improved only by 0.09 ± 0.22 (p < 0.115). Fifty-five percent of group I and 60% of group II patients had stable CDVA (within 2 lines from baseline) at 6 months. Significant improvement in vision (gain of 2 or more lines) was seen in 45% and 30%, respectively. Worsening of vision (loss of 2 or more lines) was seen only in 2 patients in group II, but none in group I. The mean CSFT improved significantly in both groups (by 162 µ and 216 µ, respectively; p < 0.001). The mean CSFT at 6 months was similar in both groups (354 µ and 311 µ, respectively; p=0.172). Conclusions Both treatments resulted in anatomical improvement of DME with concurrent VMIA. Visual improvement was more pronounced in the IVI group, although this may have been affected by other confounding factors.

Abstract
PURPOSE To evaluate the effects of epiretinal membrane (ERM) formation on the anatomic and functional results of subjects with diabetic macular edema (DME) who are receiving intravitreal aflibercept injections (IAIs). MATERIALS AND METHODS This retrospective comparative study includes 29 eyes with DME (Group 1) and 43 eyes with DME and ERM (Group 2). After three consecutive monthly 2.0 mg IAIs, subjects received monthly follow-ups and retreatment was performed if needed. Corrected visual acuity (CVA), central macular thickness (CMT), and central macular volume (CMV) parameters were recorded tri-monthly, and the 36-month follow-up was designated the primary endpoint of the study. RESULTS There was no significant difference between groups when comparing the mean ages and male-to-female ratios (p > 0.05, for both). At the baseline, the mean CVA value was significantly worse (p = 0.002), and the mean CMT was significantly lower (p = 0.016) in Group 1, while there was no significant difference in terms of the mean CMV (p = 0.625). The mean number of IAIs was similar at the first (p < 0.102), second (p = 0.363), and third year (p = 0.850) follow-ups. The mean CVA was significantly worse, and CMT was significantly lower in Group 1 at most of the visits in the first half of the follow-up period (p < 0.05, for all), while there was no significant difference in the second half of the follow-up period. There was no significant difference between groups in terms of CMV at any visit (p > 0.05, for all). CONCLUSION Despite a similar number of IAIs needed, worse baseline clinical parameters are associated with poorer early- or mid-term outcomes. At the long-term follow-up, CVA and CMT became similar in DME independent of ERM.

Abstract
Purpose: To evaluate the effects of a coexisting epiretinal membrane (ERM) on the treatment outcomes of a dexamethasone implant (DI) in diabetic macular edema (DME) patients. Methods: One hundred five eyes of 78 DME patients (44 F, 34 M; mean age: 65.7) treated with minimum 2 DIs were enrolled into this retrospective study. The study population was divided into the ERM (+) study group and the ERM (-) control group. The best corrected visual acuity (BCVA), intraocular pressure, and central macular thicknesses (CMTs) were evaluated at baseline and months 1, 2, and 3 after each DI treatment. Results: Both groups were comparable in baseline BCVA, CMT, HbA1c levels, and age. In the study group (n: 49), BCVA changed following the first DI from 0.83 to 0.76 and from 0.97 to 0.80 following the second DI. CMT decreased after the first DI from 465 to 377 μ (P < 0.001) and from 477 to 356 μ (P < 0.001) after the second DI. In the control group (n: 56), BCVA changed following the first DI from 0.81 to 0.77 and from 0.86 to 0.83 following the second DI. After the first DI, CMT decreased from 483 to 280 μ (P < 0.001) and from 468 to 301 μ (P < 0.001) after the second DI. The inter-group comparison revealed no significant difference in visual or anatomical gain (P = 0.46, P = 0.05, respectively). Conclusion: The presence of an epiretinal membrane did not change the treatment response to DI therapy.

Abstract
Diabetic macular edema (DME) is the most common cause of moderate visual loss in diabetic patients. The current treatment of choice for center-involved DME is anti-vascular endothelial growth factor (VEGF) treatment. Most patients that undergo pharmacological inhibition with anti-VEGF agents need multiple monitoring visits that include optical coherence tomography imaging and multiple injections. Despite this intensive treatment, up to 60% of eyes will have persistent DME after six consecutive monthly injections of an anti-VEGF. Its sustainability over the long term has been questioned. Pars plana vitrectomy (PPV) by increasing the vitreous cavity oxygenation, relieving vitreomacular traction, and removing cytokines from the vitreous cavity may cause long-term resolution of DME without the aforementioned concerns in selected cases. Eyes with vitreomacular traction clearly benefit from PPV as the primary treatment. The role of PPV for eyes with DME without tractional elements is less clear and needs to be explored further.

Abstract
AIMS To present an authoritative, universal, easy-to-use morphologic classification of diabetic maculopathy based on spectral domain optical coherence tomography. METHODS The first draft of the project was developed based on previously published classifications and a literature search regarding the spectral domain optical coherence tomography quantitative and qualitative features of diabetic maculopathy. This draft was sent to an international panel of retina experts for a first revision. The panel met at the European School for Advanced Studies in Ophthalmology headquarters in Lugano, Switzerland, and elaborated the final document. RESULTS Seven tomographic qualitative and quantitative features are taken into account and scored according to a grading protocol termed TCED-HFV, which includes foveal thickness (T), corresponding to either central subfoveal thickness or macular volume, intraretinal cysts (C), the ellipsoid zone (EZ) and/or external limiting membrane (ELM) status (E), presence of disorganization of the inner retinal layers (D), number of hyperreflective foci (H), subfoveal fluid (F), and vitreoretinal relationship (V). Four different stages of the disease, that is, early diabetic maculopathy, advanced diabetic maculopathy, severe diabetic maculopathy, and atrophic maculopathy, are based on the first four variables, namely the T, C, E, and D. The different stages reflect progressive severity of the disease. CONCLUSION A novel grading system of diabetic maculopathy is hereby proposed. The classification is aimed at providing a simple, direct, objective tool to classify diabetic maculopathy (irrespective to the treatment status) even for non-retinal experts and can be used for therapeutic and prognostic purposes, as well as for correct evaluation and reproducibility of clinical investigations.

Abstract
Various imaging modalities are of significant utility in the screening, grading, treatment, and follow-up of the different stages of diabetic retinopathy (DR) and diabetic macular edema. Color stereographic photography, fluorescein angiography, and optical coherence tomography (OCT) have been the gold standard for DR imaging for years. Besides these tools, newer technologies are gaining validation and popularity, such as fundus autofluorescence and OCT angiography. Furthermore, widefield retinography and ultra-widefield retinography have been introduced for a more comprehensive evaluation of the medium-far and very-far retinal peripheries, which is crucial for the assessment of the diverse manifestations of the disease. The aim of this review is to illustrate the recent advancements of the imaging systems for diagnosing DR, with a focus on the newest and noninvasive diagnostic tools.

Abstract
OBJECTIVE To compare the efficacy and safety of intravitreal ranibizumab (RZB) injections and intravitreal dexamethasone (DEX) implant in diabetic macular edema (DME) with concurrent epiretinal membrane (ERM). METHODS This was a retrospective, observational, comparative study. Medical records of DME patients with concurrent ERM were retrospectively reviewed. Seventeen eyes of 16 patients treated with 3 consecutive monthly RZB injections (RZB group) and 22 eyes of 18 patients treated with a DEX implant (DEX group) were included. The groups were compared at baseline, 1st, 2nd, 3rd and 4th months in terms of best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP). RESULTS Eighteen of the 39 eyes (46.1%) were phakic at baseline, 9 (52.9%) of which were treated with RZB, whereas 9 (40.9%) were treated with DEX implant (P=0.528). Although CMT improved significantly in both the RZB and DEX groups (P<0.001); the trend was different (P=0.003). The mean change in CMT at 1month in the DEX group was greater (DEX: 188.2±142.7μm; RZB: 95.7±110.7μm; P=0.034); it was in favor of RZB group at the 3rd and 4th months (DEX: -52.7±86.9μm; RZB: 1.4±31.4μm; P=0.012. DEX: -63±67.3μm; RZB: -5.8±43.9μm; P=0.004, respectively). BCVA improved significantly in both groups (P<0.001). There was no statistical difference between the groups with regard to gain in BCVA or IOP change throughout the study period (P=0.572, P=0.064, respectively). CONCLUSION Both RZB and DEX are effective in improving anatomical and visual outcomes in DME with concurrent ERM. The DEX group was associated with a prompt anatomic response, but with a gradual decrease from 3rd month.

Quantitative assessment of macular contraction and vitreoretinal interface alterations in diabetic macular edema treated with intravitreal anti-VEGF injections. Graefes Arch Clin Exp Ophthalmol 2018; 256:1801-1806. [PMID: 29922890 DOI: 10.1007/s00417-018-4042-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2018] [Revised: 06/04/2018] [Accepted: 06/07/2018] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Macular contraction after anti-vascular endothelial growth factor (anti-VEGF) injections for diabetic macular edema (DME) was evaluated by documenting the displacement of macular capillary vessels and epiretinal membrane (ERM) formation. METHODS A total of 130 eyes were included in this retrospective study. The study group consisted of 63 eyes which had intravitreal anti-VEGF injections for DME, and the control group included 67 eyes without central DME. The study and the control groups were well balanced in terms of diabetes duration and HbA1c. The distances between the bifurcation of the macular capillary retinal vessels were measured, and ERM status was evaluated based on spectral-OCT findings on the initial and final visit. RESULTS In the study group, the mean number of injections was 4.7 ± 2.6 (3-14). The mean follow-up time was 16.7 ± 7.8 months in the study group whereas it was 20.7 ± 10.9 months in the control group (p = 0.132). The change in distance measurements between the reference points on macular capillary vessels was significant in all lines except line c (p < 0.05 for lines a, b, d, e, and f) in the study group whereas it was significant in only line e in the control group (p = 0.007, paired samples test). However, when the change in macular thickness was accounted as a confounding factor, the change in distances between the references points from the initial visit to the final visit lost its significance (repeated measures ANCOVA, p > 0.05). During follow-up, the number of cases with ERM changed from 10 to 12 in the study group whereas it remained three in the control group. CONCLUSION There was a displacement of macular capillary vessels which was associated with the change in macular thickness in eyes having anti-VEGF injections for DME. The number of ERM cases did not change significantly during the follow-up.

Abstract
Purpose To determine whether the presence of vitreomacular interface abnormalities (VMIA) in patients with diabetic macular oedema (DMO) modifies the response to ranibizumab. Methods Medical records and spectral-domain optical coherence tomography (SD-OCT) scans of consecutive patients with centre-involving DMO initiating therapy with ranibizumab between December 2013 and March 2014 at the Belfast Health and Social Care Trust were reviewed. Patients were identified through an electronic database. Demographics; systemic baseline characteristics; history of previous ocular surgery/laser; best-corrected visual acuity (BCVA), central retinal thickness (CRT) and stage of retinopathy at presentation; and BCVA, CRT and presence/absence of fluid at the last follow-up were recorded. OCT scans were reviewed by a masked investigator who graded them for the presence/absence of VMIA at baseline and during follow-up and for the change in the posterior hyaloid face during follow-up. The association between (1) VMIA at baseline and (2) the change in the posterior hyaloid face during the follow-up and functional/anatomical outcomes was evaluated. Results One hundred forty-six eyes of 100 patients (mean age 63.5 years) followed for a mean of 9 months (range 2–14 months; only 9/146 dropped to follow-up before month 6) were included. Statistically significant differences were observed at baseline in BCVA (p = 0.007), previous macular laser and panretinal photocoagulation (PRP) (p = 0.006) and previous cataract surgery (p = 0.01) between eyes with and without VMIA, with better levels of vision, higher frequency of macular laser and lower frequency of PRP in eyes where no VMIA was present. Multivariable regression analysis did not disclose any statistically significant associations between VMIA at baseline or change in the posterior hyaloid face during the follow-up and functional and anatomical outcomes following treatment. Conclusion VMIA are associated with worse presenting vision in patients with DMO; VMIA or change in the posterior hyaloid face during the follow-up did not modify the response to ranibizumab in this study.

Abstract
Throughout ophthalmic history it has been shown that progress has gone hand in hand with technological breakthroughs. In the past, fluorescein angiography and fundus photographs were the most commonly used imaging modalities in the management of diabetic macular edema (DME). Today, despite the moderate correlation between macular thickness and functional outcomes, spectral domain optical coherence tomography (SD-OCT) has become the DME workhorse in clinical practice. Several SD-OCT biomarkers have been looked at including presence of epiretinal membrane, vitreomacular adhesion, disorganization of the inner retinal layers, central macular thickness, integrity of the ellipsoid layer, and subretinal fluid, among others. Emerging imaging modalities include fundus autofluorescence, macular pigment optical density, fluorescence lifetime imaging ophthalmoscopy, OCT angiography, and adaptive optics. Technological advances in imaging of the posterior segment of the eye have enabled ophthalmologists to develop hypotheses about pathological mechanisms of disease, monitor disease progression, and assess response to treatment. Spectral domain OCT is the most commonly performed imaging modality in the management of DME. However, reliable biomarkers have yet to be identified. Machine learning may provide treatment algorithms based on multimodal imaging.

Abstract
BACKGROUND Symptomatic vitreomacular adhesion (sVMA) is a recognised cause of visual loss and by tradition has been managed by pars plana vitrectomy (PPV). A less invasive alternative to surgery in some people is enzymatic vitreolysis, using an intravitreal injection of ocriplasmin. OBJECTIVES To assess the efficacy and safety of ocriplasmin compared to no treatment, sham or placebo for the treatment of sVMA. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 1), MEDLINE Ovid (1946 to 24 February 2017), Embase Ovid (1947 to 24 February 2017), PubMed (1946 to 24 February 2017), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 24 February 2017, ClinicalTrials.gov (www.clinicaltrials.gov); searched 24 February 2017 and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 24 February 2017. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA We included randomised controlled trials (RCTs) of people with sVMA. The intervention was intravitreal ocriplasmin 125 μg injection, and this was compared to placebo or sham injection (control). Placebo was defined as a single intravitreal injection of 0.10 mL placebo with identical drug vehicle diluted with saline. A sham injection was defined as the syringe hub or blunt needle touching the conjunctiva to simulate an injection. DATA COLLECTION AND ANALYSIS Two authors independently selected relevant trials, assessed methodological quality and extracted data. We graded the certainty of the evidence using the GRADE approach. MAIN RESULTS This review included four RCTs conducted in Europe and the USA with a total of 932 eyes of 932 participants. Participants were 18 to 97 years of age, with evidence of focal vitreomacular adhesion (VMA) on optical coherence tomography (OCT) imaging, with a best corrected visual acuity (BCVA) of 20/25 or worse in the study eye and 20/400 or better in the fellow eye. The interventions compared were intravitreal ocriplasmin versus sham (two RCTs) or placebo (two RCTs) injection. Both sham and placebo injection were classified as the control group. The main outcome measures were assessed at 28 days and six months. Overall, we judged the studies to have a low or unclear risk of bias. All four RCTs were sponsored by the manufacturers of ocriplasmin.Compared with control, ocriplasmin treatment was more likely to result in VMA release within 28 days (risk ratio (RR) 3.46, 95% confidence interval (CI) 2.00 to 6.00; 859 eyes, 4 RCTs, high-certainty evidence). Approximately 97/1000 eyes will have VMA release within 28 days without treatment. An additional 237 eyes will have VMA release within 28 days for every 1000 eyes treated with ocriplasmin (95% CI 96 more to 482 more).Treatment with ocriplasmin was also more likely to result in macular hole closure (RR 2.87, 95% CI 1.50 to 5.51; 229 eyes, 3 RCTs, high-certainty evidence). Approximately 123/1000 eyes with macular holes will have closure with no treatment. An additional 231 eyes will have macular hole closure for every 1000 eyes treated with ocriplasmin (95% CI 62 more to 556 more).Eyes receiving ocriplasmin were also more likely to have complete posterior vitreous detachment (PVD) within 28 days (RR 2.94, 95% CI 1.39 to 6.24; 689 eyes, 3 RCTs, high-certainty evidence). Approximately 40/1000 eyes will have complete PVD within 28 days without treatment. An additional 78 eyes will have complete PVD within 28 days for every 1000 eyes treated with ocriplasmin (95% CI 16 more to 210 more).Eyes receiving ocriplasmin were more likely to achieve 3-line or greater improvement in BCVA at six months (RR 1.95, 95% CI 1.07 to 3.53; 674 eyes, 3 RCTs, moderate-certainty evidence). Approximately 61/1000 eyes will have a 3-line or greater improvement in BCVA at six months without treatment. An additional 58 eyes will have 3-line or greater improvement in BCVA at six months for every 1000 eyes treated with ocriplasmin (95% CI 9 more to 154 more).Receiving ocriplasmin also reduced the requirement for vitrectomy at six months (RR 0.67, 95% CI 0.50 to 0.91; 689 eyes, 3 RCTs, moderate-certainty evidence). Approximately 265/1000 eyes will require vitrectomy at six months without treatment and 87 fewer eyes will require vitrectomy for every 1000 eyes treated with ocriplasmin (95% CI 24 fewer to 132 fewer).Treatment with ocriplasmin resulted in a greater improvement in validated Visual Function Questionnaire form score at six months (mean improvement difference 2.7 points, 95% CI 0.8 to 4.6; 652 eyes, 2 RCTs, moderate-certainty evidence).Eyes receiving ocriplasmin were more likely to have an adverse event (RR 1.22, 95% CI 1.09 to 1.37, 909 eyes, 4 RCTs, moderate-certainty evidence). Approximately 571/1000 eyes will have an adverse event with sham or placebo injection and 106 more eyes will have an adverse event for every 1000 eyes treated with ocriplasmin (95% CI 52 more to 212 more). AUTHORS' CONCLUSIONS Evidence from a limited number of RCTs suggests that ocriplasmin is useful in the treatment of sVMA. However, up to 20% of eyes treated with ocriplasmin will still require additional treatment with PPV within six months. There were more ocular adverse events in eyes treated with ocriplasmin than control (sham or placebo injection) treatment. Many of these adverse events, particularly vitreous floaters and photopsia, are known to be associated with posterior vitreous detachment. At present however, there is minimal published long-term safety data on eyes treated with ocriplasmin. Further large RCTs comparing ocriplasmin with other management options for sVMA would be beneficial.

Abstract
PURPOSE There is little information about the efficacy of intravitreal vascular endothelial growth factor (VEGF) inhibition in vitrectomized eyes. This study aimed to evaluate the efficacy of anti-VEGF (ranibizumab) on diabetic macular oedema in previously vitrectomized eyes. METHODS A nationwide retrospective review of medical records from 2010 to 2013. RESULTS We identified 33 previously vitrectomized eyes in 28 patients treated with ranibizumab injections for diabetic macular oedema. Median follow-up was 323 days (interquartile range 72-1404 days). Baseline mean visual acuity was 0.57 logMAR (95% CI 0.13-1.01) before injections. After an average of 4.7 injections (range 1-15), mean visual acuity remained stable at 0.54 logMAR (95% CI 0.13-0.95) with a mean improvement of 0.03 (p = 0. 45, 95% CI -0.12 to 0.06). In 12 eyes (36%), visual acuity improved 0.1 logMAR or more, in 12 eyes (36%), vision was unchanged (gain or loss of 0-0.05 logMAR), and in nine eyes (27%), vision decreased 0.1 logMAR or more. Mean central foveal thickness (CFT) on optical coherence tomography (OCT) scan was 412 μm (95% CI 390-434 μm) before injections. After injections, the mean CFT decreased to 352 μm (95% CI 334-370 μm). The mean reduction in CFT was 14% (95% CI 4-24%, p = 0.01). Sixteen eyes (48.5%) became devoid of oedema on the last OCT scan. Despite the significant reduction in CFT, the visual acuity remained unchanged. CONCLUSION Intravitreal ranibizumab can be effective in previously vitrectomized eyes with diabetic macular oedema. However, the response is variable and should be carefully monitored.

Abstract
PurposeTo report the incidence and associated factors for the development of vitreomacular interface abnormality (VMIA) in patients with diabetic macular edema (DME) who received intravitreal injection (IVI) of anti-VEGF (Bevacizumab and Ranibizumab) treatment.MethodsA retrospective observational study. Patients with DME followed at least 6 months were reviewed. Baseline best-corrected visual acuity (BCVA), central retinal thickness (CRT) and final BCVA, CRT in eyes with and without VMIA were compared. Multiple logistic regression was also used to investigate the risk factors of VMIA formation in patients with DME treated by anti-VEGF.ResultsA total of 201 eyes in 142 patients met the inclusion criteria of the study. VMIA developed in 44 eyes (21.89%) of patients during a mean follow-up period of 40.84 months. The estimated mean incidence of VMIA formation was 6.43% per year. Poor baseline BCVA was found to be a risk factor for VMIA development (P=0.001, odds ratio=5.299, 95% confidence interval: 1.972 to 14.238). There was no difference between eyes with and without VMIA formation in improving BCVA (P=0.557) and lowering the macular edema (eyes without VMIA formation: -107.72±171.91 μm; eyes with VMIA formation: -155.02±212.27 μm, P=0.133).ConclusionsThis study revealed the incidence of VMIA formation in IVI anti-VEGF treated DME eyes was 6.43%. Poor baseline BCVA was found to be a risk factor for VMIA formation. Both eyes with and without VMIA development had favorable response to anti-VEGF treatment.

Abstract
Purpose Intravitreal anti-vascular endothelial growth factor (VEGF) agents are effective in the treatment of central involving diabetic macular oedema (DMO). Vitreoretinal interface abnormalities (VRIA) are common in patients with DMO, and the effect of these on the response to anti-VEGF treatment is unclear. Furthermore the effect of anti-VEGF agents on the VRIA itself is uncertain. Method Prospective study of consecutive patients treated with ranibizumab (RZB) for DMO as part of routine clinical care in one eye unit over a 1-year period. Visual acuity (Va), central retinal thickness (CRT) and injection frequency data was recorded on an electronic database. Treatment was initiated with four monthly RZB injections and then a monthly PRN regime. All patients underwent high-density spectral-domain optical coherence tomography (SDOCT) at baseline and 12 months. The SDOCTs were graded by two observers masked to the outcome. Results One hundred and four eyes (77 patients) were included in the analysis. The mean age was 62 years, and 62% were male. The mean presenting vision was 62 letters and CRT 472 μm. Eighty eyes retained stable Va, and 17 had an improvement in Va. At baseline, 39 eyes had associated focal vitreomacular adhesion (VMA) and by 12 months this reduced to 30 (p = 0.04), with 12 releasing VMA and three developing it. Patients with VMA had significantly better final Va than those without VMA. Improvement in CRT was greatest in those where VMA released during the study. Forty-five eyes had some degree of foveal involving epiretinal membrane (ERM) at baseline, and 28 were considered to have clinically significant ERM. There was no clinically relevant change in ERM during the study. Patients with significant ERM at baseline had a lower final vision. Multivariate analysis showed that ERM and more severe retinopathy at baseline were predictive of less visual improvement (p < 0.01). Shorter intraretinal cyst length, ERM and the absence of VMA at baseline were predictive of a worsened anatomical response (p < 0.001). Conclusion VRIA are related to outcome in patients treated with RZB. ERM was associated with a worsened visual and anatomic response, and VMA with an improved anatomical response particularly when spontaneous VMA release occurred during treatment. The presence and severity of ERM was not affected by RZB treatment.

Abstract
Diabetic retinopathy (DR) is a leading health concern and a major cause of blindness. DR can be complicated by scar tissue formation, macular edema, and tractional retinal detachment. Optical coherence tomography has found that patients with DR often have diffuse retinal thickening, cystoid macular edema, posterior hyaloid traction, and tractional retinal detachment. Newer imaging techniques can even detect fine tangential folds and serous macular detachment. The interplay of the vitreous and the retina in the progression of DR involves multiple chemokine and other regulatory factors including VEGF. Understanding the cells infiltrating pathologic membranes at the vitreomacular interface has opened up the possibility of new targets for pharmacotherapy. Vitrectomies for DR remain a vital tool to help relieve tension on the macula by removing membranes, improving edema absorption, and eliminating the scaffold for new membrane formation. Newer treatments such as triamcinolone acetonide and VEGF inhibitors have become essential as a rapid way to control DR at the vitreomacular interface, improve macular edema, and reduce retinal neovascularization. These treatments alone, and in conjunction with PRP, help to prevent worsening of the VMI in patients with DR.
